Abstract :
We present the hybrid integration of a low-temperature-grown GaAs metal-semiconductor-metal photoconductive switch with a GaAs SEED optical modulator, for sampling input voltages with potentially >40-GHz bandwidth and performing linear electro-optic conversion at a rate >500 megasamples/sec.
